| Caesium fluoride Usage And Synthesis |
| Description | Caesium fluoride can be used as an analytical reagent, and also for the manufacture of optical crystals It can be used for the preparation of fluorinated isocyanate. During the Suzuki cross-coupling synthesis reaction, it can be used as a base for the positive substitution of the biaryls compound; it can also be used as a nucleophile for the fluorination of protic mediate such as the halide and sulfonate contained in tert-butyl alcohol or t-amyl alocohol. It can also be used as catalyst for the Silyl enol ether reaction of carbonyl compounds; used for efficient synthesis of single crystal Dion-Jacobson phase CsLaTa2O7 tto be applied to photocatalytic and superconductivity. | | Chemical Properties | white crystalline powder | | Uses | Used as a base in a Suzuki cross-coupling synthesis of ortho-substituted biaryls.5 Also employed as a reagent for nucleophilic fluorination of primary halides and sulfonates in protic media such as tert-butyl and tert-pentyl alcohols.6 | | Uses | A preperation of building block for synthesis of fluoroallylic compounds. | | Uses | Catalyst in oxidation reactions; as a solid base when adsorbed onto Celite, q.v. Fluoride source in organic synthesis. Inorganic scintillator. | | General Description | Cesium fluoride is an inorganic compound known to be a source of fluoride ion and a catalyst in organic synthesis. It has been used in many organic reactions like 1,4?elimination, desilylation, transesterification, acylation, nucleophilic aromatic substitution, etherification, cross?coupling reactions and so on. | | Hazard | A poison. | | Flammability and Explosibility | Notclassified | | Safety Profile | A poison. Incompatible
with benzenediazonium tetrafluoroborate
and difluoroamine. When heated to
decomposition it emits toxic fumes of F-. | | Purification Methods | Crystallise it from aqueous solution by adding ethanol. |
